*UPDATE*

Well she is alive! My friend and I spent a Saturday experimenting and staring at the wiring diagrams. In a last ditch hail Mary we ran 2 wires from battery--one to the fuel pump check terminal and one to the ignition coil connector. Bless her tough heart she fired right up on the first try after sitting for over a year. Seems that while proper voltage was present and measurable at these 2 points, the connection must not have been sound, which maybe didn't allow enough current to pass to make the stuff work.

So anyway, we are not quite there, as I still haven't figured out exactly what is going on. But at least I have a workaround, and maybe one of the guru's here can use this info to zero in on it. Both wires must be connected for it to run. I have to, not surprisingly, disconnect them to stop the engine as well.

Thanks everyone for all your help with this. We are close!
